Online communications company Twilio will announce the launch of its nonprofit arm Thursday during the final day of its annual San Francisco conference.

Chief Executive Jeff Lawson will unveil Twilio.org during his morning keynote at TwilioCon, a three-day summit at the San Francisco Design Concourse. The philanthropic initiative is aimed at helping nonprofits achieve greater social good through improved communications.

"We want to make sure that every nonprofit doing good knows that this technology can help them and that we're here to help then get started," Lawson said in an interview.

The company creates technology to embed Internet phone calls and messaging services into websites and mobile apps. It hopes to help qualified nonprofits send a billion messages by providing $500 in credits and 25 percent discounts on voice and messaging services.

Twilio.org represents the formalizing of the company's charitable initiatives, as it had already been working with various nonprofits including Code for America, an effort to use technology to make government more responsive to the needs of citizens. Earlier this year, Twilio teamed up with Salesforce.com, the Polaris Project and Thorn to provide a text-based tool to help victims of human trafficking, after it became clear that they could rarely find ways to make voice calls discreetly.

"So many of the problems nonprofits are solving (are) about improving communications," Lawson said.
